M28W320 datasheet

Description :

The M28W320 is a 32 Mbit (2 Mbit x 16) nonvolatile Flash memory that can be erased electricallyat the block level and programmed in-system on aWord-by-Word basis. These operations can beperformed using a single low voltage (2.7 to 3.6V)supply. VDDQallows to drive the I/O pin down to1.65V. An optional 12V VPPpower supply is pro-vided to speed up customer programming.

■ Supply Voltage
   –Vdd = 2.7V to 3.6V Core Power Supply
   –Vddq = 1.65V to 3.6V for Input/Output
   –Vpp= 12V for fast Program (optional)
■ Access Time: 70, 80, 90, 100ns
■ Programming Time
  – 10µs typical
  – Double Word Programming Option
  – Quadruple Word Programming Option
■ Common Flash Interface
■ Memory Blocks
   – Parameter Blocks (Top or Bottom location)
   – Main Blocks
■ Block Locking
   – All blocks locked at Power Up
   – Any combination of blocks can be locked
   –WP for Block Lock-Down

Description :

GP2Y0A41SK0F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector) , IR-LED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.



1. Distance measuring sensor is united with PSD, infrared LED and signal processing circuit

2. Short measuring cycle (16.5ms)

3. Distance measuring range : 4 to 30 cm

4. Package size (29.5 × 13.0 × 13.5mm)

5. Analog output type
